The bearing plate 22 is provided with bolt holes 25, from which depend the bolts 26 which carry at their lower end a supporting plate 21. The supporting plate 21 is rectangular as shown in Figure 5, and serves to support the members I5 which rest thereon. The members l5 are arranged on opposite sides of the tube It], and they are drawn towards each other by means of bolts 23 which cause them to grip the tubes frictionally. The load is thus transmitted to the tube I partly frictionally and partly through the plate 21, bolts 26 and bearing plate 22.

As will be seen the bolts 26 are arranged between the bearing members and do not pass therethrough.

In the construction shown in Figures 7, 8 and 9, the bearing plate 29 is circular instead of being elliptical and carries four of the depending bolts 26. Two of these are arranged between the bearers l and the other two are onthe outside thereof. These bolts carry the supporting plate 21 which in this construction is square, and the supporting plate carries the bearers I5 which are drawn together as before by the bolts 28.

In the modification shown in Figure 10, the bearing plate 30 is provided with downwardly projecting bolts 3| which have eyes 32 at their lower ends, and two of the bolts 28 passing through the bearers l5 extend through these eyes. It will be understood that there are two bolts 3| at each side of the pair of bearers. The upper two of the bolts 28 simply pass through the bearers, while the lower two are somewhat longer and pass through the eyes of the bolts 3| in addition to passing through the bearers.

In the modification shown in Figure 11, the bearing plate 33 is p ovided with a spigot 34 at its underside which engages within the top of the tube 0, otherwise the bearing plate is constructed as already described, and it carries the tube 2| as before.

In this case the bearing plate is provided with depending bolts 35 which carry a U shaped supporting plate 36 within which ar mounted the bearers l5. The bolts 28 in this construction passing through the bearers also pass through the sides of the plate 36.

In all the constructions wherein a supporting plate is carried beneath the bearing plate, the

I supporting plate is provided with an aperture through which the tube Ill extends.

Further, in any of the constructions herein described, means may be provided to prevent the bearing plate at the top of the tube In from turning about the axis of the tube. ,For instance, the top of the tube Ill may be notched as shown at 42 in Figure 12 and the underside of the bearing plate 22 may be provided with a lug 43 for engaging in the notch.

The present invention provides a means of transmitting the load positively from the track bearers to the understructure, and such a construction in the case of a scenic railway or the like is used at those parts of the track where the stresses and shocks are known to be greatest.

Although I have described the invention as applied to the supporting of a track of scenic railway or gravity ride, it should be understood that its application is not limited thereto and that it may be applied also to the connection together of wooden or other non-metallic members with elongated metal members where a load has to be transmitted from one set of members to the other.

What I claim then is:

1. Scafiolding structure comprising spaced pairs of vertical metal tubes forming supports, a bearing plate having a non-rocking engagement with the top of each support tube, bolts depending from said bearer plate, a supportin plate carried by the lower ends of the bolts, the support tube passing through said supporting plate, a pair of bearers arranged on opposite sides of said support tube and resting on said supporting plate, and bolts connecting said bearers without passing through the support tube and drawing said bearers into gripping engagement with said tube.

2. Scafiolding structure comprising spaced pairs of vertical metal tubes forming supports, a bearing plate having a non-rocking engagement with the top of each support tube, bolts depending from said bearer plate, a supporting plate carried by the lower ends of the bolts, the support tube passing through said supporting plate, a pair of bearers arranged on opposite sides of said support tube and resting on said supporting plate, some of said dependent bolts being placed between said bearers and some at the outer sides thereof, and bolts connecting said bearers without passing through the support tube and drawing said bearers into gripping engagement with said tube.

3. Scafiolding structure comprising a vertical metal tube forming a support, a pair of bearers engaging opposite sides of said support tube, bolts connecting said bearers without passing through the support tube and drawing said bearers into gripping engagement with said tube, said engagement locating the bearers and preventing movement thereof horizontally, a bearing plate having a non-rocking engagement with the top of said support tube, supporting means engaging said bearers, and bolts connecting said supporting means with said bearing plate, said bearing plate receiving the downward thrust on said bearers due to the load.

JOHN BURTON.
